Answer:

Option c (2.27) is the right option.

Step-by-step explanation:

As per the question, the values are:

<u>Credit hours                                       Grade                                 fiXi</u>

       (fi)                                                   (Xi)                              

<u>         4                                                  B = 3                                   12</u>

<u>         3                                                  C = 2                                   6</u>

<u>         1                                                   A = 4                                   4</u>

<u>         3                                                  D = 1                                    3       </u>

Now,

\Sigma fi= 25

\Sigma fiXi = 25

hence,

The average will be:

= \frac{\Sigma fiXi}{\Sigma fi}

On putting the values, we get

= \frac{25}{11}

= 2.27

Suppose f(x) = mx + b. What is the inverse function in terms of m and b?
katrin2010 [14]

Answer:

f^(-1)(x) = (x-b)/m  or  x/m - b/m

Step-by-step explanation:

f(x) = y = mx + b

To find the inverse function, interchange x and y and solve for y, i.e.

x = my + b

my = x-b

y = (x-b)/m = x/m - b/m
